ARRI Orbiter Docking Ring allows you to add a third-party accessory such as a projection, Fresnel, or cyc-optic to your Orbiter light. While ARRI brand Orbiter accessories don’t require a docking mount, this docking ring allows you to mount other third-party extensions onto the light using a quick and easy mounting process. The ring clamps around an accessory measuring 5.3 to 6.3″ in diameter, and it supports up to 17.4 lb. A thumbscrew tightens the clamp around the accessory, and the bayonet-style mount clamps the ring onto the front of the light. To use the docking ring, the light needs to be running at least LiOS version 1.3.
